For enhanced safety, the front and rear seat shoulder belts of the Kia K5 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 2 Series Gran Coupe doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Kia K5 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 2 Series Gran Coupe doesn’t offer height-adjustable seat belts.
Both the K5 and 2 Series Gran Coupe have child safety locks to prevent children from opening the rear doors. The K5 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The 2 Series Gran Coupe’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To help make backing out of a parking space safer, the K5 has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. BMW charges extra for Cross Traffic Warning on the 2 Series Gran Coupe.
Both the K5 and the 2 Series Gran Coupe have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, driver alert monitors and available around view monitors.
